Question 1.

The figure shown below represents the internal structure of a certain seed. Study the figure and answer the following questions.

The figure shown below represents the internal structure of a certain seed. Study the figure and answer the following questions.

(a) Identify the seed and mention whether it is mono or dicotyledonous.

(b) Label the guidelines 1 to 4.

(c) Write an important role of part 2.

(d) Mention the food component found in part 4.

(e) What kind of germination takes place in the above mentioned seed ?

Answer:

(a) It is a Bean seed that is dicotyledonous.

(b) The labelled guidelines are:

1 → Plumule

2 → Radicle

3 → Testa

4 → Cotyledons

(c) Radicle grows downward into the soil and anchors the plant, absorbing water and nutrients from the ground. It develops into the primary root of the plant, which later gives rise to the entire root system.

(d) Protein

(e) Epigeal germination

Question 2.

With regard to germination in bean seed, answer the following questions:

(a) State the function of the ‘micropyle’.

(b) Name the part of the seed that grows into the seedling.

(c) Draw a neat labelled diagram of the structure named above.

(d) Name the part of the seed that provides nutrition for the growing seedling.

Answer:

(a) The ‘micropyle’ serves two important functions:

  •  Allows absorption of water and makes it available to the embryo for germination.
  •  Enables diffusion of respiratory gases for the growing embryo

(b) The embryo of the seed grows into the seedling.

(c) Structure of embryo

Structure of embryo

(d) The cotyledons of the seed provide nutrition for the growing seedling or the embryo.
